Critics argue that NBC’s platform legitimizes the views of a man who, among other conspiracy theories, has suggested that the killing of 26 people at the Sandy Hook Elementary School in Newtown, Connecticut, in 2012 was a hoax. The network released a brief portion of the interview, which is scheduled to air on Sunday.

Kristin Lemkau, chief marketing officer for J.P. Morgan, took to Twitter to criticize the decision to conduct the interview.

"As an advertiser, I'm repulsed that @megynkelly would give a second of airtime to someone who says Sandy Hook and Aurora are hoaxes. Why?" she wrote.
